- by transverse and the upper ends of roller 15 and Referring to the drawings, the main frame of the machine comprises parallel, longitudinally extendin side frames 2 and 3 connected ars 4 and 5; and supported upon the floor 7 which sup orts the side frames 2' and 3. Arranged s ightly beyond the side frames 2 and 3 the forward or feed end of the machine are two supplementary side frames 8 and 9 which form, in effect, a

art of the main frame of the machine.

The sheet of aper 10 to be acted upon by the machine is rawn from a roll of aper 11 carried b a shaft 12 which extends tween and whic is sup orted by the supplementary side frames 8 an 9. The end portions of the shaft 12 project beyond the ends of the roll 11 and are inserted into hearings in the frames 8 and 9 from above the same, the bearings being open at the top to permit the end portions of the shaft to be readily lowered into them when a fresh roll of paper is supplied to the machine.

' The sheet of paper 10 from the roll 11 asses beneath a straightening bar. 13 and P u wardly therefrom to and between a pair continuously operated feed rollers 14 and 15. From the feed rollers .14 and 15, the paper 10 passes down and around the bottom of a take-u roller 16, thence upwardly to and over a gui 'ng roller 17 thence downwardly to and beneath two spaced guiding rollers 18 and 19, thence upwardly to and over laterally spaced forming rollers 20 on .a shaft 21, thence downwardly to and beneath a guiding roller 22, and thence to and between a lower intermittently actuated feed roller 23 and upper laterally spaced feed rollers 24 carried by a shaft 25. The guiding rollers 17, 18, 19 and 22, the shaft 21 and the feed roller 23 are mounted to turn in suitable bearings secured upon the side frames 2 and 3.

The feed rollers 14 and 15 are provided with co-acting gears 26 and 27 to cause the upper roller 14 to be driven by the lower they are mounted to turn in bearings or brackets secured upon the side frames 2 and 3. The upper roller 14 has its trunnions extending into vertical slots in the bearings therefor so as to have vertical movement toward and from the lower roller 15 the slots are open to permit the easy removal of the roller 14 from its brackets and its application thereto when a fresh sheet of paper is placed between the rollers. The lower roller 15 isserrated and the upper roller 14 rests upon the paper 10 passing between the rollers to press the paper against the lower roller 15 and cause the feeding of the paper when the lower roller is driven.

One trunnion of the lower feed oller 15 extends outwardly and is provi with a friction driving disc or wheel 28 the outer surface of which is engaged by a friction driving wheel 29 which is splined on a shaft 30 to be rotated thereby and to be longitudinally adjustable thereon. The shaft 30 extends longitudinally of the machine with its axis intersecting the axis of the feed roller 15 and its disc 28, and the shaft 30 is journaled in bearings which are secured to and project outwardly The rearward end portion of the shaft 30 is provided with a miter gear 31 in mesh with a similar gear 32 on one end portion of a shaft 33 which extends transversely of the machine and turns in suitable bearin s on the side frames 2 and 3. The other end portion ofthe shaft 33 is provided with a pinion 34.

which meshes with a gear wheel 35 on a shaft 36 extending transversely of the machine befrom the side frame 2.

neath the shaft 33 in parallel relation thereto. The shaft 36 is journaled in hearings on the side frames 2 and 3 and its gear wheel 35 is in mesh with a pinion 37 on the primary driving shaft 38 of the machine. This shaft 38 extends transversely between and turns in suitable bearings on theside frames 2 and 3,

and it is provided with a driving pulley.33

which may be driven from any suitable source of power.. have shown the pulley 39 as being driven by a belt 40 which passes around the same and a pulley on the power shaft of a suitable electric motor 41.

It will now be understood that when current is supplied to the motor 41, the shafts 30, 33, 36 and 38 will be driven thereby and that the friction wheel 29 will rotate the disc 28 and the feed rollers 14 and 15 in the direction of the arrows in Fig. I and thereby cause the rollers 14 and 15 to draw the paper 10 from the roll 11 and feed it into the machine continuously.

The hub 42 of the friction driving wheel 29 has an annular oove therein containing a collar 43 (Fig. I which is embraced by and connected to a bifurcated arm 44 which extends from one end portion of a relatively short screw threaded shaft 45 located above the shaft 30 in parallel relation thereto. This shaft 45 is screwed into and through a bearin 46 which projects outwardly from the si e frame 2. The shaft 45 is fitted to turn in the arm 44 and the arm 44'is located be tween two collars fixed to one end portion of the shaft 45. The other end portion of the shaft 45 carries a hand wheel or head 47 by means of which the shaft 45 may be turned. By turning the hand wheel 47 the friction driving wheel 29 may be moved longitudinally on the shaft 30 either toward or from the axis of rotation of the lower feed roller 15 to decrease or increase the speed of rotation thereof and thereby decrease or increase the speed of the continuous feed of the paper 10 by the rollers 14 and 15.

The bearings 48 for the trunnions of the lower intermittently operated feed roller 23 have vertical guideways formed in the up- As herein illustrated I.

mamas per portions thereof for the reception of vertically movable bearing blocks 49 for the shaft 25 carrying the upper feed rollers 24;

and the shaft and roller 23 are provided with co-operating gears 50 and 51 (Fig. X) which cause the rollers 24 to be actuated when the roller 23 is actuated. The vertical guideways in the bearings 48 permit the bearing blocks 49 and shaft 25 and rollers 24 to be moved toward andfrom the lower feed roller 23. The shaft 25 and therewith the upper feed rollers 24 are constructed to be pressed toward the lower feed roller 23 to ensure the feeding of the paper 10 by the rollers by screws 52 which are screwed into and through blocks 53 carried by a bar 54 which extends between and is secured to arms rising from the bearings 48. The lower ends of the screws 52 are seated in sockets in bosses projecting upwardly from collars 55 on the shaft 25 and the upper ends of the screws are provided with wing heads 56 by means of which the screws may be turned by hand to regulate the pressure of the rollers 24 upon the paper The trunnion 57 on one end of the feed roller 23 extends outwardly and has a ratchet wheel 58 secured thereto; and oscillatable on the trunnion 57 between the ratchet wheel 58 and a disc 60 secured to the outerend of the trunnion 57 is a bearing member 64, a gear wheel 63 and a wheel or disc 61 secured to the gear Wheel 63. The bearing member 64 is provided with a guideway 65 for the reception of the upper end portion of a bar 66 which is fitted to slide longitudinally therein. The end portion of the bar 66 which slides within the bearing member 64 is provided with gear teeth forming a rack 67 which is in mesh with the gear wheel 63. The lower end portion of the bar 66 is pivoted on a crank bolt 80 carried by a crank 81 secured to the outwardly projecting end of the power driven shaft 36 hereinbefore referred to, whereby, when the shaft 36 is rotated, the upper end portion of the bar 66 will be longitudinally reciprocated through the guideway in the bearing member 64, rocking the member 64 on the trunnion 57 and causing the gear rack 67 to impart a forward and back oscillatory movement to the gear wheel 63 and disc wheel 61 on the trunnion 57. The disc wheel 61 is provided with a projecting pin 68 on which a pawl 69 is pivoted and arranged to engage the ratchet wheel 58 and impart a forward movement to it and to the feed rollers 23 and 24, when the wheels 63 and 61 are moved forwardly, and to be disengaged from the ratchet wheel 58 when the wheels 63 and 61 are moved backwardly. It will thus be understood that, during the operation of the machine, the bar 66 operated by the crank 81 on the continuously revolving shaft 36, will impart an intermittent feeding movement to the feed rollers 23 and 24 in the direction of the arrows in Fig. III.

To movethe pawl 69 into and from engagement with the ratchet wheel 58 during the forward and back movements of the wheels 63 and 61, and to hold the pawl 69 out of contact with the teeth of the ratchet wheel 58 during the entire backward movement of the wheels 63 and 61 I provide the following means: Projecting from the pawl 69 is a pin 7 O which is located inwardly of the pin 68 toward the trunnion 57 and which extends into a. slot 71 formed in the free end portion of an arm 72 projecting from a collar 73 on the trunnion 57 between a collar 59 thereon and the ratchet wheel 58. The collar 73 is split. and provided with projecting arms which are connected by a bolt 76 by means of which the collar 73 may be contracted upon the trunnion 57 Connected to the collar 73 and extending therefrom around the trunnion 57 between it and the inner surface of the collar 73 is a strap 77 of leather or other suitable friction producing material. The bolt 76 is adjusted to contract the collar 73 and clamp this strap 77 between it and the hub 59 to produce sufiicient friction to cause the collar 73 and arm 72 to be turned by and with the ratchet wheel 58 when it is turned in one direction, and to permit the wheel 58 to be turned relativel to the collar 73 when the collar 73 is held against movement and the wheel 58 is turned in the reverse direction.

The arrangement of the pins 68 and relativelyto each other and to the axis of the roller trunnions 57, and the friction between the strap 77 and the collar 73 and ratchet wheel hub 59 is such as to cause the following operation: During the initial forward movement of the disc wheel 61, as shown by the arrow 78 in Fig. XXI, the arm 72 prevents the pin 70 from moving with the wheel 61 until the pin 70 causes the pawl 69 to be rocked on the in 68 from the inoperative position shown by dot-and-dash lines in Fig. XXI to the o erative position, shown by full lines in Fig. XXI in which the furthermove- {)nenfi of the pawl 69 on the pin 68 is prevented y t of the ratchet wheel 58, whereupon, during the remainder of the forward movement of the wheel 61, the pawl 69 turns the ratchet wheel 58 and therewith the collar 73 and roller trunnion 57 forwardly. During the initial backward movement of the disc wheel 61, as shown by the arrow 79 in Fig. XXI, the arm 72 prevents the pin 70 from moving with the wheel 61 until the pin 70 causes the pawl 69 to be rocked'on the pin 68 from the operative position shown by full lines in Fig. XXI to the inoperative position shown b dot-and-dash lines in Fig. XXI in which the further movement of the pawl 69 on the pin 68 is stopped by the engagement of the pawl 69 with a pin 84 on the wheel 61, whereupon,

the wheel 61, as previously explained.

, adjusting The crank bolt 80 extends through a slot in the arm 81 and the bolt is adapted to be secured to the arm 81 indifferent positions of adjustment toward by clamping the arm 81 between a fixed collar 82 and an adjustable nut 83 on the the bolt 80 on the arm 81 to different positions toward and from the shaft 36 the extent of movement of the paper strips 91 at each intermittent movement thereof may be varied.

It will now be understood that during the operation of the machine the sheet of paper 10 will be drawn from the roll 11 by the feed rollers 14 and\15 and fed forwardly in the (ill direction of the arrows in Figs. I and III by the rollers 14 and 15, and by the feed rollers 23 and 24 and that the rollers 14 and 15 will feed the paper continuously while the rollers 23 and 24 will feed the paper intermittently. During the intervals of time between the feeding operations of the rollers 23 and 24, the slack produced in the paper 10 is taken up between the feeding rollers 14, 15 and guiding roller 17 by the take-up roller 16 which is supported byand within the loop of paper formed between the rollers 14, 15 and the roller 17, and which is raised by the paper during each feeding operation of the rollers 23 and 24, and which is lowered by gravity while the rollers 23 and 24 are idle and the rollers 14, 15 continue to feed the paper, thus keeping the paper drawn taut and under the proper tension at all times. The ends of the take-up roller 16 are provided with trunnions which rest against inclined bars 85 on the side frames 2 and 3 and guide the roller 16 during its up and down movements.

The straightening bar 13' is provided to remove from the sheet of paper 10 its tendency to curl and in some measure to retain the curvature of the roll 11 from which it is drawn. This bar 13 rests upon the. roll 11 and has its respective end portions extendin into guiding slots or ways 86 in arms 87 formed on and projecting upwardly from the supplemental side frames 8 and 9. These slots 86 guide the bar'13 during its descent by gravity as the diameter of the roll 11 grows less as the paper is drawn therefrom. The paper 10 is drawn upwardly from the straightening bar 13 to the feed rollers 14, 15, thereby forming an obtuse angle in that portion of the paper which extends upwardly from the bar 13 and that portion of the paper on the top of the roll 11 which is moving toward the bar 13. The angle thus formed and from the shaft 36 in the aper kinks or bends it reversely of the curve condition of the paper produced by the roll 11 and thereby straightens the paper so that the product of the machine will be straight and flat. The straightening effect of the bar 13 upon the paper 10 is dependent upon the obtuseness or acuteness of the angle produced in the paper by the bar 13; that is to say, the greater the tendency of the paper to curl or retain the curvature of the roll 11 the more acute must be the angle produced in the paper by the bar 13. Therefore, as the inner portions of the paper of the roll 11 bolt. By tend to curl or retain the curvature produced therein by the roll to'a greater extent than the outer portions of the paper, I set the arms 87 and the slots 86 therein in such relation to the roll 11 and feed rollers 14 and 15 that the angle produced in the paper'by the bar 13 willgrow more acute as the diameter of the roll 11 diminishes in size and the bar 13 moves down through the slots 86 following the top of the roll, resulting in straightening all parts of the paper of the roll to the desired extent.

In Fig. XXV I have shown a top view of the sheet of paper 10 from the region of the guiding rollers 17 and 18 to and beyond the intermittent feed rollers 23 and 24 the center of which is indicated by the line a. As the paper passes through the machine it is acted upon therein by devices hereinafter described, first, to produce longitudinal score lines 88 in the sheet at the line a; second, to produce longitudinal score lines 89 in the sheetat the line 5; third, to trim waste strips 90 from the longitudinal edge portions of the sheet and to cut the sheet longitudinally into a plurality of strips 91 at the line a; fourth,

to turn one longitudinal edge 94 of each strip 91 downwardly and inwardly beneath the main body of the strip on its score line 89 in the region of the line 03; fifth, to punch spaced pairs of holes 92, 93 through the main body and the downwardly and inwardly turned edge portion 94 of each strip 91 at the lines e, e; and, sixth, to cut the strips 91 transversely at the line 7 and thereby produce the loose leaves 95, shown in Fig. XXV, which are the product of the machine and which are produced in numbers corresponding with the numbers of the strips 91 at each cutting operation on the line f.

As the sheet of paper 10 passes between the guide rollers 18 and 19 it passes first between upper and lower shafts 96 and 97, then between upper and lower shafts 98 and 99, and then between upper and lower shafts 100 and 101. The lower shafts 97 99 and 101 turn in bearing brackets 102 on the side frames 2 and 3 and the upper shafts 96, 98 and 100 turn in bearing blocks 103 which are vertically adjustable in guides formed in the upper portions of the brackets 102. Each block 103 is provided with a downwardly rests upon the bracket 102.

nuts 104, the upper shafts may be raise and lowered into alinemen't and into proper positions relatively to the lower shafts. Each bracket 102 has a top plate secured thereon and provided with a set screw 105 constructed to be tightened against the underlying hearing block 103 to secure it in its adjusted position. The upper shafts 96, 98 and 100 are provided with gear wheels 106 which co-act with gear wheels 107 on the lower shafts 97, 99 and 101 to cause the upper shafts to be rotated by and with the lower shafts. The lower shafts 97, 99 and 101 project outwardly at one side of the machine and are provided with miter gears 108 in mesh with similar gears 109 on a shaft'110 which extends longitudinally of the machine and is fitted to turn in suitable hearings on the side frame 3 thereof. This shaft 110 carries a miter gear 111 meshing with a. similar gear 112 secured on the outwardly projecting end of a trunnion on the lower intermittent feed roller 23,

whereby, the shafts 96, 97, 98, 99, 100 and 101 will be intermittently turned in the directions of the arrows by and in harmony with the intermittent actuations of the feed rollers 23 and 24, previously described.

The shafts 96 and 97 carry split collars 113 and 114, respectivel which are provided with clamping bolts or screws and which are constructed to be secured to the shafts different positions of longitudinal adjustment thereon to permit them to be set in different positions transversely of the direction of travel of the sheet of paper 10. The paper 10 passes between the collars 113 and 114 and there is a collar 113 and a collar 114 for each score line 88 produced in the paper. The collars 113 have smooth, peripheral, annular ribs 115 thereon which press the paper 10 into annular grooves 116 in the collars 114 for the formation of the score lines 88 in the paper.

The shafts 98 and 99 carry collars 117 and 118, respectlvely, which are constructed to be secured thereto in different positions of adj ustment thereon similarly to the collars 113 and 114. The paper 10 passes between the collars 117 and 118 and there is a collar 117 and a collar 118 for each score line 89 produced in the paper 10. The collars 117 have. relatively sharp, toothed or serrated, periph-.

eral, annular ribs 119 which press the paper 10 into annular grooves 120 in the collars 118 for the formation of the score lines 89 in the paper.

The shafts 100 and 101 carry collars 121 and 122, respectively, which are constructed to be secured thereto in different positions of adjustment thereon similarly to the collars 113 and 114. There is a collar 121 and a collar 122 for each longitudinal cut 123 (Fig. XXV) in the sheet of paper 10, and the colthe machine above lars'121 and 122 carry co-actin'g beveled, lapping cutting discs 124 and 125, respectively, which produce the cuts 123 in the aper l0 and which cut the strips 90 from t e edges thereof as the paper is drawn between the discs.

The shaft 21 is rollers 20 one for each strip of paper 91 and the rollers 20 are set with relation to the strips 91 so that each score line 89, Fig. XXV, will have a peripheral edge portion of a roller 20 directly beneath it and the remainder of the roller extending back under the adjacent scoreline 88 and beneath the main body of the paper strip. Now, as the strips of paper 91 pass over the rollers 20, the tension on the paper between the forming rollers 20 and the guiding roller 22 causes the edge portions 94 of the strips 91 to bend downwardly, on the score lines 89. As the paper strips 91 pass from the forming rollers 20 to the uiding roller 22 their turned down, lateral e ge portions 94 are folded inwardly beneath the body portions of the strips 91 by fixed folding fin gers or arms 126 which extend beneath the edge portions of. the strips. The folding fingers or arms 126 are supported by and extend from a bar 127 which extends transversely of the path of travel of the paper strips 91 and has its respective end portions secured to the side frames 2 and 3.

Arranged between the guiding roller 22 and the intermittent feed rollers 23 and 24 are two parallel frames 128 carrying the devices for punchi the holes 92, 93 in the paper strips 91. s these frames and the hole punching devices associated with each are the same, a description of one will suffice for both. Each frame 128 comprises two end brackets 129 resting upon the side frames 2 and 3, and a bar 130 extendingtransversely of the machine between and secured to the lower portions of the end brackets 129. Ex tending between the end brackets 129 above and parallel to the bar 130 is a vertically movable bar 131 having its respectiveend portions fitted to slide in vertical slots or ways in the end brackets129. The bar 131 is provided with upwardly extending yokes 132 which enclose a long cam or eccentric 133 formed on or secured to a shaft 134 having its end portions fitted to turn in hearings in the upper end portions of the brackets 129. he cam or eccentric 133 is adapted to engage the top of the bar 131 and lower it when the shaft 134 is rocked in one direction and to engage the yokes 132 and raise the bar 131 is rocked in the reverse provided with forming 135 (Fig. XIII) corresponding in number with the paper strips 91. Each punch or die 135 is carried by a block 136 which is carried by a pair of bolts 137. Each bolt 137 has a flared head on one end thereof fitted I 151 are tightened and thereby draw the rib -149 down upon to an undercut longitudinally extending groove in the bar 131, and each bolt .137 has a nut screwed on to the other clamp the block to the bar 131 to set the block in different positions of adjustment transversel of the line of travel of the paper. Each lock 136 has a boss 138 formed thereon into which the upper portion of the punch 135 is screwed to be supported thereby and to be vertically ad'usta screw 139 is screwe into the to of the boss 138 to form an adjustable stop or the punch 135 and to be tightened against the same to lock it in position. I Screwed on to the lower end ortion of the boss 138 is a sleeve 140 whic forms in effect a part of the boss and extends downwardly 140 has an inwardly extending annular flange 141 on the lower end thereof ada .ted to be en aged by an outwardly exten ing annular ange 142 onthe upper end of a vertically movable sleeve 143 which enters the lower end portion of the sleeve 140 and rojects below the bottom thereof. The ower portion of the punch 135 is reduced in diameter and it extends through the sleeve 140 and into a central bore in the sleeve 143 to a point near the bottom thereof. A spring 144 encircles the unch 135 within the sleeve 140 between the hottom of the boss 138 and the top of the sleeve 143 and holds the flange 142 normally against the flange 141. The punch 135 is adapted to be depressed against the action of the spring 144 relatively to the sleeve 143 as and for'a purpose hereinafter described.

The bar 130 carries a set of die blocks 145 corresponding in number with the punches 135 and located beneath the same. These blocks 145 rest upon a ledge 146 and against a vertical wall 147 formed by the bar 130, and the blocks 145 are ad'ustable along the ledge 146 transversely o the direction of movement of the paper strips 91. Each block 145 has an outwardly ,extendin r1b 148 on the lower portion thereof over w 10h extends a rib 149 on the upper portion of a clamping bar 150 which is secured to the bar 130 by means of ca screws 151. The lower portion of the c amping bar 150 has a beveled rib 152 thereon adapted to engage an oposing beveled surface on the bar 130 to draw he bar 150 downwardly when the screws the rib 148 and hold the blocks'145 firmly in place upon the bar 130.

Each block 145 has a vertical bore extending therethrough towhich is fitted a bushing 153 having an annular flange 154 on the lower end thereof countersunk into the block 145. The upper end portion 155 of the bushing is contracted and forms a female die in vertical alinement with the punch 135 above the same. The up er end portion 156 of a plunger 157 is fitte to slide vertically end thereof to letherein. A set.

The plunger 157 has a collar 159 formed thereon and arranged to engage the bottom of the contracted portion 155 of the bushin 153 and limit the upward movement 0% the plunger 157. The collar 159 is held normally against the contracted ortion 155 by a spring 160 which encircles t e plunger 157 between the collars 158 and 159 and against which the plunger is adapted to be depressed, as will be presently described.

The aper strips 91 pass between the bars 130 an 13, and the folded edge portion 94 of each strip passes between a punch and a die block-145 when the bar 131 of each frame 128 is lowered, the sleeves 143 will engage the paper and force it down upon the die sleeves 153 against the action of the springs 144 and clamp the folded edge portlons 94 and the bodies of the paper strips 91 together while the punches 135 are forced on down through the paper and into the die sleeves 153 and thereby punch the holes 92 and 93 in the paper. As the punches enter the die sleeves 153, the plungers 157 therein are forced down agirinst the action of the springs 160, and, w en the punches 135 are raised from within the sleeves 153, the lungers 157 ejectthe paper discs cut by 't e punches 135 and sleeves 153 from wlthin the latter. v

I shall now describe the mechanism for rocking the shafts 134 to lower and raise the punch carrying bars 131 for effecting the hole punching operations. The ends of the shafts 134 project outwardly at one side of the machine and they are rovided with arms 161 having the upper en s of links 162 pivotally connected thereto. The lower ends 'of the links are pivoted to the projecting ends of pins 163 w ich are fitted to turn in the outer end portions of arms 164 projectin outwardly from a shaft 165 which exten s longitudinally of the machine and which turns in hearings on the side frame 2. The pins 163 form universal joint connections between the links 162 and arms 164 to permit the adjustment of the frames 128 as will be presently described. The shaft 165is provided with an inwardly projecting arm 166 (Figs. I, III and VIII) which is pivotally connected to a vertically movable lock 167 which extends between and above and below the shafts 33 and 36, the block 167 having vertical slots therein through which the shafts extend. The block 167 slides vertically between two cams 168 and 169 secured on the driving shaft 36, and the ,block 167 is guided in'its vertical movement by the cams 168 and 169 and by the walls of the slots in the block 167 engaging the shafts 33 and 36. The block 167 is portion of the m a collar or is screwed mto the bushing 135 beneath the same, so that rovided with pins which" reject outwardly rom opposite sides thereo and bottom of the cams 168 tively, to cause the cams to the block 167 and 196, respec lower and raise and thereby rock the shaft which rocks the shaft 134 to lower and raise the punch carrying bars 131.

The end brackets 129 ofthe frames 128 carrying the devices for punchin the holes 92, 93 in the paper strips 91 are ad ustable on the top of the side frames 2 and 3 longitu-' dinally thereof to vary the distance between the frames 128 and to adjust the-frames relatively to the other mechanism of the machine and the brackets 129 are adapted to-be -se-' cured to the side frames 2 and 3 in different positions of adjustment thereon by clamps or yokes 172 which embrace. the bottom portions of the upper bars of the side frames 2 and'3 f and the top of foot flanges on the brackets 129. These clamps 172 are rovided with set age t e side frames 2 and 3 and force the c amps 172 downwardly to clamp the brackets. i v;.

Extending transversely of the machine in advance of the intermittent feed rollers 23 and XVIII) the respective ends are secured to the brackets or bearings 48; and extending parallel to the bar 173 and beneath the path of travel of the paper strips 91 is a bar 174 having its end cured to arms 175 portions sewhich extend from the bar 173. The bar 173 with rearwardly extending brackets 176 which are secured thereto by means of screws 177 which may be screwed into different holes in the bar 173 to permit them to be adjusted to different positionstransversely of the machine. The brackets 17 6 correspond in number with the paper strips 91 and they are provided with rearwardly and downwardly inclined spring wire fingers 178 which are shaped and positioned as shown in the drawings. The free ends of the'fingers 178 press lightly upon the paperstrips 91 in the path of travel of the perforations 92, 93 therein and the end portions of the fingers 178 are adapted to enter the perforations during the passage thereof beneath the fingers and eject from the perforations any paper discs which may lodge therein, ing operations.

he upper'intermittent feed rollers 24 are b adjustable on the shaft 25 to different positions transversely of the machine and they correspond in number with the paper strips 91 and they are set in position on the shaft 25 to engage the single thickness of the strips 91 away from the downwardly and inwardly turned edge portions 94 thereof for the unib form pull upon the paper strip 10 during the intermittent feeding thereof.

The paper strips 91 are fed forwardly by theintermittent feed rollers and carry rollers-- 170 and 171 which are engaged by the top 'zontal, as shown in Fig. XII, downwardly is providedv blade.

as a result of the punch-- between upper and lower paper guidi bars 179 and l80 (Figs. III and Hg 23 and 24 to and XV) andto and between the upper and lower cutting knives 181 and 1.82 of a paper, cutting device which I shall now describe. The guiding bars 179 and extend between and they are secured 1 to thelowerfportions of brackets 183 which rise fixedly om the side frames 2 and 3. The upper end portions of the brackets 183 are connected by a bar 184 whichhas its end portions secured thereto. The upper knife blade 1'81 is-secured-to and carried by a vertically movable bar 185 which extends transversely of the machine below the bar 184 and has its respective end portions fitted to slide in vertical slots or we. s 186 in the brackets .183. The bars 184 and 185 are connected by parallel-motion links 187 and 188 which are ivoted to the bars 184 and 185 to guide the ar-185-and maintain it in parallel relation to the bar 184. The link-187 is provided with an outwardly projecting arm 189 which is connected bya link 190 toan arm 191 which extends outwardly-from the rockable shaft 165 hereinbefore referred to, whereby, when the shaft 165 i and 24 is a bar 17 3 (Figs. II, III, XVI, XVII,- b

of which is rocked, the upper cutting lade 181 will be raised and lowered. v The lower or cutting edge 192 of the upper cutting blade 181 is inclined or set at anangle with relation to the upperior cutting edge of the lower cutting blade 182 which-is horiso that when the blade 181 the links 187 is lowered it and 188 to the left handside of will be swung b the machine, as shown in Fig. XI, to cut the paper strips 91 extending between the blades 181 and 182 by a shearing action. The end portion of the upper blade 181 at the lower end of its cutting edge is provided with a downwardly directed 'GXtGIISIOD 192 which extends below the top of the lower blade 182 when the upper blade 181 is in its uppermost position and which is in contact withjthe forward surface of The lower blade 182 is supported upon a bar 194 (Fig. XV) secured to the bar 180, and the blade 182-is pressed yieldingly toward the blade 181 by springs 195v interposed between the bar 180 and the blade 182. These springs 195 encircle bolts 196 which extend through the bar 180 and limit the movement of the blade 182 toward the path of the blade 181. series of these length of the blade 182,

It will now blade extension 192 and continuing to' the opposite side of the machine and thus ensure a close contact of the cutting edges of the blades at the cutting point during the entire cutting or shearing operation.

The cutting operation just describedtakes place at the line f indicated in Fig. XXV after each advancement of the paperstrips 91 by the intermittent feed rollers 23 and 24, and, at each cutting operation, a set of leaves 95 corresponding in number with the paper strip 91 are cut therefrom. As the sets of leaves 95 are thus out they fall from the cutting edges of the blades 181 and 182 upon the rearward end portions of a set of conveyer tapes 198 which pass around rollers 199 and 200 carried by shafts 201 and 202 which turn in hearings on the side frames 2 and 3 and on brackets 203 respectively, extending therefrom. The sets of leaves 95 fall upon one another and form piles or stacks thereof upon the tapes 198 each a predetermined number of leaves counted containing by mechanism of the machine presently described; and upon the completion of each set of piles of leaves, the tapes 198 are advanced in the direction of the arrows in Figs. II and III to advance the completed piles a sufficient distance to clear the space in front of the blades 181 and 182 for the reception of the next set of piles. As the piles of leaves are thus successively advanced by the tapes 198 the piles are removed from the tapes by hand.

I shall now describe the mechanism for counting the leaves 95 as they are cut from y the strips 91 and for intermittently actuatwheel 207, and loosely to be engaged by two pawls 209 ing the tapes 198 to advance the piles o counted leaves from the cutting blades.

The-shafts 201 and 202 are provided with sprocket wheels connected by a sprocket chain 204 the lower portion of which passes over a sprocket wheel 205 which is loosely mounted on a shaft 2% extending between the frame brackets 203.,Fixed to the sprocket wheel 205 adjacent to one side thereof is a ratchet mounted on the shaft 206 adjacent to the ratchet wheel 207 is a ratchet wheel 208 containing the same number of teeth as the ratchet wheel 207. The two ratchet wheels 207 and 208 are adapted and 209", respectively, formed on a single arm 209 which is pivoted on an arm 210 mounted to be rocked on the shaft 206. The arm 210 is pivoted to one end of a bar 211 the other end of which is pivoted to one arm 212 of a lever 213 by means of a pivot bolt 214 exon the power The-lever arm 217 is held against the cam shaft 36 previously described.

moved toward and from the ratchet wheel 58 to engage and disengage the same, as hereinbefore described; and'for this purpose I provide an arm 72 and pins and 84 which operate in the same relation to the pawl arm 209, arm 210 and shaft 206 as the arm 72 and pins 70 and 84 o erate with relation to the pawl 69, disc w eel 61 and trunnion 57 respectively. I

The ratchet wheels 207 and 208 are each provided with fifty teeth and the space between every fifth tooth of the ratchet wheel 207 and the tooth next adjacent thereto is deepened from the normal line and any number of these deepened spaces may be occupied by blocks 221 to destroy the efiect of the adjacent deep teeth 223 by bringing the deepened space adjacent thereto out to the normal line of the ratchet wheel. These blocks 221 are removably secured to the ratchet 207 by screws 222 and any number of the blocks 221 may be removed as desired for purposes presently appearing.

When the arm 210 is rocked forward and back by the cam 218 the pawl 209 will engage the ratchet wheel 207 and turn it on the f shaft 206 at each active stroke of the arm'210,

and the awl 209 will be permitted to engage an turn the ratchet wheel 208 only at such active strokes thereof when the pawlv 209 is in registry with one of the deep teeth 223 of the ratchet wheel 207 from which the adjacent block 221 has been removed, the absence of the block permitting the pawl 209". to move into active relation to the ratchet wheel 208. The throw of the pawl carrying arm 210 under the influence of the cam 218 is such that at each active stroke of the arm 210 the pawl 209 will move the ratchet wheel 207 a distance equal to the space between nine of its teeth; in other words, during successive strokes of the arm 210 the pawl 209 engages every ninth tooth of the ratchet wheel 207 so that if but one of the blocks 221 be removed from its adjacent tooth 223, as shown at 224 in Fig. XXIII, the ratchet wheel 208 will be moved by the pawl 209? only at each fiftieth active stroke of the arm 210, when the pawl 209" isbrought into registry with the tooth 223 adjacent to the deep space 224 for the actuation of the ratchet, because nine will not divide evenly into fifty.

The timingof the operation'of the cam 218 is such thatit gives an active stroke to the 208 in the same manner that the pawl 69 is i
